(Submitter supplied) The Arabidopsis thaliana mutant wrky33 is highly susceptible to the necrotrophic fungus Botrytis cinerea. We identified by ChIP-seq >1680 high-confidence WRKY33 binding sites associated with 1576 genes within the Arabidopsis genome, with all of them being dependent on rapid activation of WRKY33 expression by Botrytis cinerea strain 2100. Genome-wide transcriptional analysis defined 318 genes as direct functional targets at 14 h post inoculation. more...

(Submitter supplied) The Arabidopsis thaliana mutant wrky33 is highly susceptible to the necrotrophic fungus Botrytis cinerea. Comparing the expression profiles of B. cinerea-infected wrky33 and WT plants we identified 2765 differentially expressed genes dependent on WRKY33, of which 1675 were up-regulated in the mutant (termed WRKY33-repressed genes) and 1090 were down-regulated in the mutant. Combined with ChIP-seq data 318 genes were identified as direct functional targets of WRKY33 at 14 h post inoculation with spores of Botrytis cinerea 2100.

(Submitter supplied) The goal of the microarray experiment was to identify defense genes that were differentially expressed in the Arabidopsis mutants med16, med8, elp2, wild type in response to infection of the necrotrophic fungal pathogen Sclerotinia sclerotiorum. Results indicated that, compared with the wild type, the jasmonic acid (JA) biosynthesis genes LOX3, AOC3, and OPR3, ethylene (ET) biosynthesis genes ACS2 and ACS8, as well as salicylic acid (SA) biosynthesis genes ICS1 and EDS5 were up-regulated in med16 in local tissues at 1 day post-inoculation (dpi) and/or systemic tissues at 4 dpi. more...

(Submitter supplied) Transcriptional reprogramming forms a major part of a plant's response to pathogen infection. Many individual components and pathways operating during plant defense have been identified but our knowledge of how these different components interact is still rudimentary. We have generated a high-resolution time series of gene expression profiles from a single Arabidopsis leaf during infection by the necrotrophic fungal pathogen, Botrytis cinerea. more...

(Submitter supplied) A novel experimental design strategy (A Mead et al, in preparation), based on the principle of the “loop design”, was developed to enable efficient extraction of information about key sample comparisons using a two-colour hybridisation experimental system. With 192 distinct samples (four biological replicates at each of 24 time points in mock and treated conditions) to be compared, the experimental design included 288 two-colour microarray slides, allowing four technical replicates of each sample to be observed. more...

(Submitter supplied) ced2 mutant has reduced expression of NCED3 in response to osmotic stress (PEG, polyethylene glycol) treatments compared to the wild type. Other ABA biosynthesis genes are also greatly reduced in ced2 under osmotic stress. We used microarrays to detail the global programme of gene expression under osmotic stress treatment and identified distinct classes of up/down-regulated genes in the stress pathway.

(Submitter supplied) STO2 is a novel MYB like protein which belongs to one of the most important transcription factors in planta. Microarray analysis of sto2 null mutant compared to Columbia with three-week-old soil-grown plants revealed that STO2 function in ABA and salt stress response.

(Submitter supplied) Composts are the products obtained after the aerobic degradation of different types of organic matter wastes and can be used as substrates or substrate/soil amendments. There are a small but increasing number of reports that suggest that foliar diseases may be reduced when using compost as growing medium compared to standard substrates. The purpose of this study was to unravel the gene expression alteration produced by the compost to gain knowledge about the mechanisms involved in the compost-induced systemic resistance. more...

(Submitter supplied) In this study, we have identified genes that are respectively activated and repressed by the low concentration of ABA and show that ROP10 gates a specific subset of genes that are responsive only to a low ABA concentration.

(Submitter supplied) Using a transgenic line expressing HA-tagged ATAF1 uncovered >400 ChIP-seq peaks in ATAF1-HA plants compared to Col-0 wild-type plants. Only a small sub-set of the candidate peaks could be verified using ChIP-qpcr or EMSA. Among the verified peaks we uncovered the key ABA biosynthetic gene NCED3 as a target of ATAF1
